Title:
INFRARED HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/088764
Kind Code:
A1
Abstract:
Provided is an infrared heating device which has a high degree of freedom with respect to heating region shape setting, such as being able to set island-like low-temperature regions, when a shield member is placed away in a non-contacting manner from a member to be heated, without it being necessary for the rigidity of the shield member to be ensured. Because a retainer member (16) which allows near-infrared light (L) to pass through is disposed between infrared lamp heaters (12) and the member to be heated (14) and the shield member (18) is held by the retainer member (16), the shield member (18) can be placed away from the member to be heated (14), and heating of the shield member (18) due to heating of the member to be heated (14) can be suppressed, thereby preventing early deterioration of the shield member. In addition, the degree of freedom in setting the shapes of high-temperature heating regions (Hi) and low-temperature heating regions (Lo) is improved, for example, island-like low-temperature heating regions (Lo) can be formed by using island-like shield members (18b, 18c). Also, because there is no need to support the shield member (18) in a cantilevered manner, the plate thickness of the shield member (18) does not need to be increased to ensure rigidity, so the infrared heating device can be inexpensively constructed.
